In 2015, a piece of equipment at an observatory in the US moved one quintillionth (10-18) of a meter. This tiny movement was the first recorded event of gravitational waves. And it helped confirm ...

The universe occasionally produces a huge surprise that proves physicists wrong, says Kip Thorne, who grew up in Logan, Utah, ...

As Hurricane Helene slammed into Florida on September 26 as a Category 4 hurricane, it brought destruction and death across the U.S. Southeast. The storm claimed over 230 lives, making it the ...

A study published in Nature has established a new benchmark in modeling the universe's most extreme events: the collisions of black holes and neutron stars. This research, led by Professor Jan Plefka ...

In 2023, physicists were awed to find nearly imperceptible ripples in the fabric of space and time — united as an entity known as spacetime. They were ripples discovered in association with ...

Einstein's theory of gravity, general relativity, has passed all tests with predictions that are spot-on. One prediction that remains is "gravitational wave memory"—the prediction that a passing ...

The Earth’s atmosphere is host to a diverse spectrum of wave phenomena, among which acoustic-gravity waves occupy a pivotal role. These waves arise from the interplay between compressional (acoustic) ...
